"""Recompute the copy bot's per-wallet p80 conviction floors from the cache.

Keeps config.json's `follow.per_wallet_min_usd` in exact parity with the
dashboard's "top 20% by stake" gate as the watched wallets keep trading — using
the same cache.conv_cutoff() (p80) over each wallet's own bet sizes that the
pipeline and trading/index.html use. Only the *floors* are rewritten; the
curated watchlist itself is never touched.

Reads the wallet set from config.json's "watchlist" (falls back to "watch"), so
if you re-curate the portfolio the floors follow automatically. config.json is
gitignored, so this stays local and is never committed.
